IMPROVEMENT IN SHINGLES.

Specification forming part ot' Letters Patent N o. 177,865, dated May 23, 1876; application led l April 24, 1876.

To all 'whom it may concern Be it known that I, MARSHALL McGoMB, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Shingles; and I do hereby declaro the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification, in which- Figure lis a view illustrating the present method of marking after thel completion of one or two courses. Fig. 2 shows two forms of my invention in perspective.

This invention relates to improvements in shingles; and consists in scoring or marking the coursing-lines 7 on each individual shingle at the time of manufacture, or after, so that no time is lost in chalk-lining the courses, but the shingles may be nailed on Without any delay.

At 'present the workmen lay their rst course at the eaves of the roof, and when that course is completed across they measure oi' two courses more, and mark them all across by means of a chalkline. Then they lay the two courses next in order on these lines, and

y so on, measuring and marking the coursing lines in pairs.

Now, this entails much unnecessary labor,

I and this is increased where there are dormerwindows and other obstructions to a continuous line. If the roof be steep, the workmen endanger their lives upon it under any circumstances, and the danger enhances if they are compelled, every few minutes, to get up and go from side to side for the purpose of establishing their coursing-lines properly.

Again, as only two courses are or can be laid from one measurement,more unnecessary delay arises from the inevitable fact that one man is sure to be a faster worker than his fellow; consequently he will have his share done before the other, but must waitin idleness till the other is also done, in order to run the next lines.

Now, I propose to do away with all these difcnlties by placing the coursing-lines 011 cach shingle before bundling,either on one or both sides or edges, and so enable a' man to work right ahead, regardless of what his helper or helpers may be doing, and still preserve faultless accuracyin the weathercourses.l

lent, for if the wood be abraded with a saw` or scorer it affords `an entrance for the atmosl phere, and consequently has a tendency to rot at that point. The shingles thus lined are bundled as usual, and leave the mechanic nothing to do but nail them down. This can bc done by any one, since each shingle carries its own coursing-line, and they can be laid by one -workman without any attention to what another is doing, and he can run his side of the roof clear up to the comb without any delay. Hence no time is lost in marking ot't' the courses with a chalk-line, and no risk is undergone by running needlessly over the root'.` No delay is caused by dormerwindows or other obstructions to the continuity of the courses.

The marking could be easily done automatically by having an endless belt running alongside a guide, constituting a V-shaped trough. The shingles carried by the belt, with their butts toward the guide, could be readily marked by a iiXed pencil above or below as they passed along.

The invention is equally applicable to clapboards of any kind, in a similar way, and so does away with all guides and devices for effecting uniformity in applying. l

Having fully described my invention, I claiml. As a new article of manufacture, a shin- This line l i In testimony that I claim the foregoing I vhave hereunto set my. hand this 10th day of April, 1876.
